How to export display from an vagrant Linux box to MacOS host?

I've got a Mac OS with Catalina installed. In this MAC Os host, I run a VirtualBox centos linux box (installed with Vagrant). In the Centos virtual Box I want to launch app like (google-chrome or any x application) with the display exported to the MacOS host.
I've set the X11Forwarding yes in /etc/ssh/sshd_config (in MacOS Box AND in the Centos BOX).
On MacOS i've installed and running XQuartz, which is working well (I can start xterm from MacOs XQuartz configuration for example).
I ssh from MacOs into my Centos box with -X. So X11 port forwarding must be ok.
When I start any graphical application from Centos (google-chrome for example), I always have this message :
(google-chrome:26817): Gtk-WARNING **: 17:49:49.940: cannot open display:
I've tried some export DISPLAY configuration but without success : always cannot open dispay
Any help would be greatly appreciated because I'm stuck.
I solve my problem. It is just a matter of NIC interface used when starting VM through Vagrant. If I use the Wifi NIC -> KO. If I use the Ethernet NIC it is ok.

How do I make ssh connection between macOS and Windows with bluetooth?

I want to make ssh connection between macOS and Windows(exclude Windows Subsystem for Linux, I'm asking about just Windows) with bluetooth.
Is there a way to do it?
I want to work Both Computers as a client and server.
In macOS, I'll use pre-installed ssh and sshd command, And https://github.com/PowerShell/Win32-OpenSSH/ use as windows ssh toolset.
I apologize that I am Japanese so My English is broken.
The following is environment of my computers.
(PC)
OS: Windows 10 Home x64
Bluetooth adapter: Intel Dual Band Wireless-AC 7260 for Desktop 7260HMWDTX1.R
(Mac)
Hardware: Mid 2012 MacBook Pro
OS: macOS 10.12.6
Supporting Bluetooth version: 4.0 (it maybe wrong?)
No, it is not possible to make an SSH connection over Bluethooth. SSH requires TCP / IP and Bluethooth does not support TCP / IP.

Xming window not showing (Solaris/Windows)

I am trying to launch an install wizard window from a Solaris 9 system on my Windows 7 host to install Sybase ASE but the window won't show.
I am using Putty, with X11 forwarding enabled, and Xming on my Windows host. I am getting no error from the Solaris system. It just says Running InstallShield Wizard... and on my Windows, when I try to exit Xming it says There are currently 1 clients connected.
So clearly, my Solaris is connected to Xming, but I can't see the window.
You have to allow the solaris server to connect to the XMING config file by adding the server IP Address in the file X0.hosts (XMING install folder) then restart the XMING server on your PC. If it still does not work, try running "xhosts +" from Solaris command and export DISPLAY=your_server_IP_Address:0.0.

Accessing machine through wifi

I have one computer running ubuntu operating system. It is having a wifi router connected to it. I have other laptop which runs windows 7 operating system.
Is there a way to access the ubuntu machine from windows machine through wifi and vice versa ?
You can use TeamViewer in both windows and linux. It will give you full control of the remote machine but I'm not sure if you can do file transfering...
For file transferring, connecting from windows to linux I would use winSCP, which access files through ssh, so you would have to install an run sshd on your linux box. If you haven't sshd in your ubuntu box, install it by doing $ sudo apt-get install ssh. You can start ssh daemon in ubuntu 11.10 with the command $ sudo service ssh start. From linux (Ubuntu 11.10) to windows (w7), I have successfully got into w7 machines in my local network by exploring the Network section in the left bar of the nautilus explorer. Sometimes, for some folders it would ask me for credentials to log into the remote machine, and file transferring was as simple as doing copy and paste (Ctrl+c, Ctrl+v)
hope to be helpful! good luck!
VNC is good for remote work on both Windows and Linux. You'll need to install VNC on Windows but I believe it comes by default with Ubuntu. You need to configure one to be the server and then you can use a client from the other machine to connect to it and remotely control the server machine.
Here are some resources for VNC in Ubuntu: https://help.ubuntu.com/community/VNC
And I use TightVNC when I'm working on Windows (server and client included in the install).
Install XRDP on Ubuntu.
on windows then run msrtc -v
if over the internet , I say use
https://www.dwservice.net/en/download.html
free and lot better than teamviwer.
